Molecular-size electrical wires will soon be a reality. Researchers from the Institut Charles-Sadron (CNRS, Strasbourg) successfully coated polymer semiconductor P3BT, or poly(3-butylthiophene), fibers with insulating nanotubes by two-dimensional self-assembly of liquid esters using a heterogeneous germination process. Researchers at INAC used atomic-force microscopy and transition-voltage spectroscopy to characterize the electrical wire obtained. They demonstrated that […] >>

Researchers at INAC, Leti, and LTM recently developed a novel single-cell bacterial identification method that uses a SOI nanophotonic optical structure that concentrates light to produce a very intense electromagnetic field that can attract and trap a single bacterial cell. Fluctuations in the intensity of the light transmitted by the optical structure due to interactions […] >>

The EU-funded INSPEX project was set up to develop portable guidance systems for low-visibility conditions. Coordinated by Leti, the project, which kicked off in 2017, is expected to result in systems for humans as well as for light drones and robots. The bulk of the research will focus on miniaturizing and reducing the power consumption […] >>

Leti unveiled a new micro-LED display at Photonics West in January 2017. The 873 x 500 pixel display has a pixel pitch of 10 microns and is the fruit of four years of research and development. The technological breakthrough is based on a patented self-aligned fabrication technique that requires one lithography step to create all […] >>

When it comes to atomic moirés, appearances can be deceiving. The wavy patterns are caused by the vertical movement of atoms and interference from electronic waves in the crystals. Researchers from Institut Néel, the CEA, and Grenoble-Alpes University joined forces to show that the moirés, when viewed using a scanning tunneling microscope, did not show […] >>
